Joey Barton, of Fox Bank Close, Widnes, was charged after an alleged post-match clash in the tunnel at Oakwell following Barnsley’s 4-2 win over Barton’s Fleetwood Town on April 13.
It is alleged that Barton shoved Stendel in the tunnel, leading to his injuries which included a damaged tooth.
Barnsley complained to the Football Association and English Football League about the incident.
Barton, 37, appeared via video link at Sheffield Crown Court on Wednesday where a trial date of June 1 was set, which is expected to last for five days.
